Switch normal/inverse operation--IVS
(Function code data = 21)
Turning the IVS command on/off switches the output frequency control between
normal (proportional to the reference frequency components) and inverse operation
for the PID process or manually reference frequencies. To select the inverse op-
eration, turn the IVS command on.
When the PID control is enabled, turning the IVS command on inverts the PID
process control selected by function code J01. For example, if the PID process
control is normal, turning it on switches it to inverse, or vice versa.
Enable communications link via RS-485 (option)--LE
(Function code data = 24)
Turning this terminal command ON assigns priorities to frequency commands or run
commands received via the RS-485 communications link (H30) (option).
No LE assignment is functionally equivalent to the LE being ON.
Reset PID integral and differential components--PID-RST
(Function code data = 33)
Turning on the PID-RST command resets the PID integral and differential com-
ponents.
Hold PID integral component--PID-HLD
(Function code data = 34)
Turning on the PID-HLD command holds the current inverter output voltage con-
stant by suppressing an increase of PID integral component.
Run forward--FWD
(Function code E98/E99 data = 98)
If the FWD command is turned on, the inverter runs the motor forward; if off, it
decelerates the motor to a stop.
Run reverse--REV
(Function code E98/E99 data = 99)
If the REV is turned on, the inverter runs the motor in reverse; if off, it decelerates
the motor to a stop.
